To all whom it may concern:

Be it known that I, FERDINAND GERHARD WIEOHMANN a citizen of the United States, residing at N ew York city, county and State of New York, have invented a Process of Treating Vegetable Albumen and Animal Casein and the Product Therefrom, of which the following is a specification.

In my Patent No. 883,995, dated April 7, 1908, I have described a process of treating vegetable albumen with animal casein to bring about ac'h'emical combination and produce a roduct which in many respects simulates ru ber.

The product so obtained, may

' In each form, the product is heavier than water, and if sub'ected to the action of waterfor some time, w1ll be somewhat affected.

The purpose of my present invention is- First: to change the specific gravity of the final product rom one heavier than water to one lighter than water. Second: to render such product impervious to the action of moisture or water. The process by which the productis obtained, which is described in my former application, consists in subjecting vegetable albumen to the action of a solution of animal casein.

To carry my present invention into efiect, the product of such rocess is first brou ht into a state of fine division in any suitable manner, as by scraping, cutting or shredding, after which it is immersed in a solutionof hydrogen peroxid of approximately three (3%) per cent. strength; or, I may immerse such divided body in a solution in which hydrogen peroxid is generated in the nascent state, from chemicals or by electrolytic action. Within a few minutes after immersion in the hydrogen peroxid, about 3 to 9 minutes, the body lightens perce tibly in rises to the surface of the solution. It is then at once removed and pressed or molded into any form desired, and dried. In this condition, the material exhibits and retains its lighter color and possesses a specific gravity less than that of water, so'that it will float on water. v

To render the product impervious to moisture or water, I immerse the product, either in its primary state or in its secondary state,

In practice, I have found that the product itself has an abrading value, which especially fits it for use in connection with abradinglmaterials as above described.

aving thus described my invention, I claim:

1. The process of treating the product of the character described to render it lighter than water, which consists in subjecting it to the action of hydrogen peroxid.

2. The process of treating the product of the character described to render it lighter than water, which consists in subjecting it while in a finely divided condition to the action of hydrogen peroxid.

3. The process of treating the product of the character described to render it impervious to moisture or water, which consists in dsubjecting it to the action of formaldee. 4. The process of treating the product of the character described to render it lighter than water and impervious to moisture or water, which consists in subjecting it to the flcton of hydrogen peroxid and formaldee. 5.
